I'm trying to find information on a gate valve I've used in the past. What I remember of the valve is that it had either a coarser thread, or double thread that allowed the stem/gate to close or open twice as a fast as a normal threaded valve. Does anyone know the type of valve I'm talking...
I may have left it out, but we do utilize a preheat train of exchangers before the crude goes into the desalters, so that the temp is almost always between 230 and 290, but I was thinking more along the lines of treating it before it gets to our charge tank so that much of the bs&w is knocked...
Thank you again for all your input. Elguero, I am interested in learning more on your findings from CA. I've read a little on the diatomaceous filtering but heard that it was expensive, and wasn't sure @ what rate that would have to be replenished or replaced. Sounds like a clay tower...
In my experience as an operator, it's extremely frustrating to have a room full of people in the control room talking and hanging about when the units are in upset, let alone an emergency. The control room should only be used as a muster point when the emergency conditions prevent contract...
I appreciate you both replying. First, one thing that we are looking at is improving our desalter operation, but we're a coastal refinery that processes many different crude types, making it difficult to have good desalter operations at all times, so that's still in the works. So what I have...
Orenda,
I appreciate you taking the time to reply. We currently do utilize a DAF system. The problem is that when we do have carry under from the Desalting system, due to the minimal capacity of the canals, and the weir that is supposed to keep the oil layer from carrying into the water...
Hi folks,
I'm trying to get information on upgrading our wastewater system. We currently process up to around 5000bbls/day of waste water and are looking to revamp the whole system. One question I have is if height of a tank and volume outweigh surface area when trying to separate oil from...
